Today’s Best MLB PrizePicks Player Predictions
Andrew Heaney Under 2.5 Strikeouts
Looking at Heaney's numbers throughout the season, you'll find plenty of three-strikeout performances. However, when you look at what he's done lately, you'll see that there is no reason to take this over.
Heaney has thrown zero strikeouts in his last three appearances. In his last nine appearances, he has failed to strike out more than two batters once. The Diamondbacks were the fourth-best team at avoiding strikeouts in the regular season. Though they've started to strike out more in the postseason against better pitching, they've still fared pretty well against starters. Additionally, Heaney hasn't pitched longer than 4.2 innings since August 29th. He may end this game with zero strikeouts.
Marcus Semien Under 0.5 Runs
Semien hasn't hit a home run this postseason. Perhaps, as someone who hit 29 during the regular season, he's due, but we think that his streak will continue. The reason we bring that up is because tonight, if he's going to score a run, he may need to hit a home run.
Last night, Semien scored on a Corey Seager home run. It was his third in four games. But Adolis Garcia, the Rangers real power hitter, suffered an injury in Game 3. It pulled him from the game. While he could still play tonight, the odds of him being his usual self in less than 24 hours aren't high. That means a massive bat in the Rangers' lineup is going to be missing or hindered. And that bat has driven in Semien for two of his last four runs.
Ketel Marte Over 1.5 Total Bases
Marte has hit safely in all 15 of his postseason games. He's gone over 1.5 total bases in nine of his 15 games, and tonight, he has a decent matchup against Heaney. He's 2-6 against him in his career, with both his hits home runs.
In Heaney's last 11 appearances, only once has he pitched more than 4.0 innings. That means Marte will likely only get one or two shots against the starter. However, with how Marte is hitting, this is a prop that very easily could hit in the first inning.
